Looking at this property there is no way it was built as a Fairfield. It is just too cheaply built and fixtured of a property. If you look at things like the doors, the fixture types used for the breakfast counters, and the spacing of common areas including the tiny front desk this was definitely not a Fairfield build.
It was a build of whatever chain had that rounded logo/sign because it obvious this is a conversion based on the sign frame being a unique shape, but not the Howard Johnson shape.
Kind of seems like it could have been built as an independent.
